lisp

After reading Practical Common Lisp I finally understood what the big deal about macros was, and I have been looking for a language for the .NET platform that supports this. There are a few lisp dialects for .NET but from what I have been able to gather all are either very beta or abandoned. Recently my interest has been sparked by Clojure, but it's for the java platform and while on probably could use ikvm it doesn't feel some integrated. Especially when you want to do stuff like WPF. Recently I have been hearing whisper about F#, I tried to look at the documentation if I could find anything

I want to have sort of indiacator at left side of the line wherever I have in the source code #TODO : some comment //TODO: some comments The indicator could be a just mark and I already enabled line numbers displayed at emacs. This command will do something like you want. (defun annotate-todo () "put fringe marker on TODO: lines in the curent buffer" (interactive) (save-excursion (goto-char (point-min)) (while (re-search-forward "TODO:" nil t) (let ((overlay (make-overlay (- (point) 5) (point)))) (overlay-put overlay 'before-string (propertize "A" 'display '(left-fringe right-triangle)))))))

There are tons of tutorials on how to curry functions, and as many questions here at stackoverflow. However, after reading The Little Schemer, several books, tutorials, blog posts, and stackoverflow threads I still don't know the answer to the simple question: "What's the point of currying?" I do understand how to curry a function, just not the "why?" behind it. Could someone please explain to me the practical uses of curried functions (outside of languages that only allow one argument per function, where the necessity of using currying is of course quite evident.) edit: Taking into account

Is it legal to call a C compiler written in C or a PHP interpreter written in PHP metacircular? Is this definition valid only for languages of a specific type, like Lisp? In short, what are the conditions that an interpreter should satisfy for being called Metacircular? A metacircular interpreter is an interpreter written in a (possibly more basic) implementation of the same language. This is usually done to experiment with adding new features to a language, or creating a different dialect. The reason this process is associated with Lisp is because of the highly lucid paper "The Art of the

I was wondering if anyone has tried somehow calling Jython functions from within Clojure, and how you went about doing this if so. I have not used Jython, but I would imagine the Jython interpreter can be invoked in the same way as any other java code, and Python programs can be run within it. However I wonder if it would be possible to somehow call individual python functions from Clojure. Like I said, I have not tried this yet, so it might actually be straightforward and obvious. I'm just wondering if anyone has tried doing this. Thanks, Rob A note: I just realised that the question is
